Raven's progressive matrices
Raven's progressive matrices is a nonverbal test series which aids in assissing mental ability by requiring the examinee to solve problems presented in abstract figures and designs. The test correlates well with comprehensive intelligence tests and is highly correlated with Spearman's g. The Mill Hill vocabulary scales provide a measure of acquired verbal knowledge that supplements nonverbal reasoning ability information yielded by Raven's progressive matrices
